Non-Return Backdraft Damper
It is a high-efficiency damper designed to ensure one-way airflow and prevent backflow. By preventing unwanted reverse air currents particularly in ventilation networks, it contributes significantly to safe and efficient system performance.
Specifications
- Intended Use: Providing unidirectional airflow and preventing backflow
- Casing Material: Galvanized steel or aluminum casing options
- Blade Structure: Lightweight aluminum blades, optimized for low pressure drop
- Operating Mechanism: Opens automatically with airflow; closes by spring or gravity in case of reverse flow
- Installation: Easy integration into circular duct systems
- Maintenance: Minimal maintenance requirement for moving parts, long operational life
Application Fields
- Central ventilation systems
- Heating and cooling lines
- Industrial air ducts
- Zones requiring non-return airflow across office, residential, and commercial buildings
Advantages
- Ensures system safety by completely preventing reverse airflow
- Increases energy efficiency with low pressure drop
- Quiet and automatic operation
- Durable material build ensuring extended service life
- Easy installation and low maintenance advantages
